Module augmentation not working with moduleResolution: bundler

There seems to be an issue with module augmentation and the exports field in package.json added in https://github.com/JedWatson/react-select/pull/5559 and improved in https://github.com/JedWatson/react-select/pull/5626. Module augmentation as described at https://react-select.com/typescript#custom-select-props appears to no longer work since react-select/dist/declarations/src/Select appears to no longer be the path of the Select module when the exports field in package.json is used during module resolution. I was unfortunately not able to figure out what the new path is. Deleting the exports field from package.json fixes the issue and module augmentation works as expected again.

The relevant section of building with tsc's traceResolution option enabled:

Seems like the root cause is ./dist/declarations/src/Select' missing from the exports map:

Export specifier './dist/declarations/src/Select' does not exist in package.json scope at path '/Users/fabian/projects/brmlabs/brm/node_modules/react-select'.

Inspect react-select's package.json exports map and the module-augmentation.d.ts entry point shown in the traceResolution output. Reproduce with TypeScript's moduleResolution: bundler and traceResolution enabled; done means the documented module augmentation resolves without deleting the exports field.
